This commit includes:
1). Moves rbd errors from internal/util/errors to internal/rbd/errors.
2). Introduces ShouldRetryVolumeGroupGeneration helper function to determine
whether volume group generation should continue based on specific error types.
The function returns true if the error is of type ErrPoolNotFound,
ErrRBDGroupNotFound, ErrPermissionDenied. (Ceph user might not have access to
all the objects/pools where mapping exists)

The attribute and variable `csiID` ise used for at least two different
things:
- name of the driver instance, used for journalling metadata
- objects of the CSIIdentifier struct, composing a volume-handle
By changing the name of the `csiID` attribute for driver instances to
`driverInstance`, any confusion should be prevented.

We should return NotFound status if the group doesn't exists
for ControllerGetVolumeGroup RPC call.
And, an empty/OK response for DeleteVolumeGroup if the group
doesn't exists

There is no need for the `Manager.DeleteVolumeGroup()` function as
`VolumeGroup.Delete()` should cover everything too.
By moving the `.Delete()` functionality of removing the group from the
journal to the shared `commonVolumeGroup` type, a volume group snaphot
can use it as well.

This commit adds support for flattenMode option
for volumegroup.
If the flattenMode is set to "force" in
volumegroupreplicationclass parameters,
cephcsi will add a task to flatten the image
if it has parent before adding it to the group.
This enable cephcsi to then mirror such images
after flattening them.

With the ControllerGetVolumeGroup operation the caller can verify that a
VolumeGroup exists, and validate the volumes that are part of it.

The ModifyVolumeGroupMembership operation can be used to change the
volumes that are part of a VolumeGroup. Only empty VolumeGroups can be
removed, this operation is required to make that possible.

Add extra error checking to make sure trying to create an existing
volume group does not result in a failure. The same counts for deleting
a non-existing volume group, and adding/removing volumes to/from the
volume group.
